USS Adroit (AM-82)
USS ''Adroit'' (AM-82/PC-1586) was an acquired by the United States Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships. ''Adroit'' was laid down on 31 July 1941 at Portland, Oregon, by the Commercial Iron Works; launched on 21 February 1942; and placed in commission on 28 July 1942. Pacific Ocean operations Following her commissioning, the minesweeper moved to San Francisco, for final fitting out and shakedown training. She left the west coast on 23 November and shaped a course for Hawaii. ''Adroit'' reached Pearl Harbor on 6 December and spent two weeks undergoing voyage repairs. She set sail on the 21st for Nouméa, New Caledonia. Upon her arrival there, the ship began operations with Destroyer Squadron 12 on antisubmarine patrols off Nouméa. Guadalcanal operations In mid-April, ''Adroit'' sailed to Espiritu Santo to undergo repairs. This work was completed in June, and she got underway on the 18th with a convoy for ...

Commercial Iron Works
Commercial Iron Works was a manufacturing firm in Portland, Oregon, United States. Established in 1916, the company is best remembered today for its contribution to America's Emergency Shipbuilding Program during World War II. The company was founded in November 1916, by William T. Casey, Otto J. Hoak and Robert Boogs, on a site on the Willamette River just south of the Ross Island Bridge. Little is known about the company's early years, but it appears to have served diverse markets. For example, it placed a bid for the manufacture of 200 fire hydrants for the City of Portland in 1927, and supplied the high pressure outlet gates for the Unity Dam on the Burnt River near Baker, Oregon in 1937. The company is recorded as having built only one ship prior to World War II - a small 140-ton tender for the US Coast Guard in 1935. The CIW built the 25-ton tugboat Constance J for the Crown Willamette Paper Company. The Constance J was still in service as an active workboat as late as ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Manus Island
Manus Island is part of Manus Province in northern Papua New Guinea and is the largest of the Admiralty Islands. It is the fifth-largest island in Papua New Guinea, with an area of , measuring around . Manus Island is covered in rugged jungles which can be broadly described as lowland tropical rain forest. The highest point on Manus Island is Mt. Dremsel, above sea level at the centre of the south coast. Manus Island is volcanic in origin and probably broke through the ocean's surface in the late Miocene, 8 to 10 million years ago. The substrate of the island is either directly volcanic or from uplifted coral limestone. Lorengau, the capital of Manus Province, is located on the island. Momote Airport, the terminal for Manus Province, is located on nearby Los Negros Island. A bridge connects Los Negros Island to Manus Island and the provincial capital of Lorengau. In the 2000 census, the whole Manus Province had a population of 50,321. The Austronesian Manus languages are sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Hebrides
New Hebrides, officially the New Hebrides Condominium (french: link=no, Condominium des Nouvelles-Hébrides, "Condominium of the New Hebrides") and named after the Hebrides Scottish archipelago, was the colonial name for the island group in the South Pacific Ocean that is now Vanuatu. Native people had inhabited the islands for three thousand years before the first Europeans arrived in 1606 from a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós. The islands were colonised by both the British and French in the 18th century, shortly after Captain James Cook visited. The two countries eventually signed an agreement making the islands an Anglo-French condominium that divided New Hebrides into two separate communities: one Anglophone and one Francophone. That divide continued even after independence, with schools teaching in either one language or the other, and with different political parties. The condominium lasted from 1906 until 1980, when New He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convoy
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer cou ...
